* if you have solar-powered landscape lights and are without power AFTER a storm you can charge them outside during the day and use them inside at night by sticking their spikes into a bucket filled with sand or gravel. (Don't forget to bring them inside before a storm if possible to avoid damage).
*You can re-use empty 2-liter bottlles to store water. (According to several government agencies: fill the container with a chlorine solution of one gallon of hot water and one tablespoon of un-scented chlorine bleach, let sit for 30 seconds, empty and fill with fresh tap water leaving little or no air at the top.) Store in cool, dark closet. If freezing, leave some room at the top for expansion.
*LED lights often use less power than conventional lamps so batteries last longer
* In an emergency if cell service is out in your area, going to a high spot (porch, top of a bridge such as the Card Sound Road bridge in the Keys) can enable you to reach other more idstant towers.
